GRAPHICAL TECHNIQUE FOR DETERMINING THE ELASTIC MODULI OF A TWO-LAYER STRUCTURE FROM MEASURED SURFACE DEFLECTIONS (ABRIDGMENT)

THE FOLLOWING CONCLUSIONS ARE SUPPORTED BY THE STUDY RESULTS: (1) A FIGURE HAS BEEN DESIGNED BY MEANS OF WHICH A SET OF OBSERVED SURFACE DEFLECTION DATA CAN BE COMPARED RAPIDLY AGAINST DEFLECTIONS COMPUTED IN ACCORDANCE WITH TWO-LAYER ELASTIC THEORY. (2) THE CHART CAN BE USED TO INDICATE WHETHER A GIVEN SET OF DEFLECTIONS CORRESPONDS TO AN ELASTIC SYSTEM HAVING ONE LAYER (HOMOGENEOUS) OR TWO OR MORE LAYERS. IN THE HOMOGENEOUS AND TWO-LAYER CASES, IT PROVIDES A MEANS FOR DETERMINING THE MODULUS VALUES REQUIRED BY THE THEORY OF ELASTICITY TO ACCOUNT FOR THE OBSERVED DEFLECTIONS. (3) IN CERTAIN SPECIFIC CASES, THE FIGURE CAN BE USED TO DETERMINE THE LAYER THICKNESS IN ADDITION TO THE MODULI, BUT MORE GENERALLY THE LAYER THICKNESS MUST BE SPECIFIED TO OBTAIN UNIQUE VALUES FOR THE TWO MODULI. (4) EXTENSION OF THE TECHNIQUE TO MORE THAN TWO LAYERS IS FEASIBLE.
